Description

In OpenVZ, the host see all guest processes, and in particular cf-agent execution. So its cf-agent believe it goes wild, and kills all the other cf-agent.

The problem is more global, as promises relying on processes checks are probably not returning what we expect (example, services management)

We could add a script to use the proper values, and have CFEngine use it
However, I'm not sure how to identify the local system ... Olivier, do you know if we must use 0, or a specific number per node ?

Hi Nicolas,

If this is the same as Virtuozzo (which is based on OpenVZ), you can run this to see node-level processes:

vzps -E 0

for example:

vzps -E 0 aux

-E flag specifies to show processes for a specific container ID (CTID), and CTID=0 is always the node on Virtuozzo/OpenVZ.

Hope this helps. For any Virtuozzo questions in future feel free to ping me.

While 0 is the host, vzprocps tools are not necessarily installed by default, so you may not have official tools to check

Here's some examples to work this out without tools.

Detect an openvz host: filexists("/proc/vz/version")
This file should only exist on a host...

Extract nodeID from process status:

egrep '(Name|envID)' /proc/215706/status
Name: rsyslogd
envID: 0

egrep '(Name|envID)' /proc/930944/status
Name: httpd
envID: 11

Everything else than envID: 0 should be ignored

I've dug within the CFEngine code. Unfortunately, there isn't even a detection of openVZ within, nor hard classes for this

So we'd need to change:

in sysinfo.c : OSClasses(void)
classes.c to add new hard classes, and command per os

Ok, there's a pull request on CFEngine to detect OpenVZ :

Updated by Nicolas CHARLES over 10 years ago

Chef & Puppet don't seems to have something to detect if process run on the container or the host ( http://projects.puppetlabs.com/issues/2390 )

BTW, the prefered method to detect the openVZ env seems to be :

if there is /proc/bc/0, then it's the container
if there is a /proc/vz, then it's host

Hi Nicolas,

BTW, the prefered method to detect the openVZ env seems to be :

if there is /proc/bc/0, then it's the container

if there is a /proc/vz, then it's host

You've got this the wrong way around.

+if File.exists?("/proc/bc/0")
+  virtualization[:system] = "openvz" 
+  virtualization[:role] = "host" 
+elsif File.exists?("/proc/vz")
+  virtualization[:system] = "openvz" 
+  virtualization[:role] = "guest"

/proc/bc/0 directory exists on the node-level (host) on OpenVZ/Virtuozzo/Parallels Cloud Server so that's correct.

The elseif is also correct, /proc/vz directory does exist at container-level (guest) on OpenVZ/Virtuozzo/Parallels Cloud Server and we already established it's not the host.

Thanks

I'm thinking of a quick and dirty solution
If the file /proc/bc/0 exists, then we move /bin/ps to /bin/distrib_ps, and define /bin/ps to be

#! /bin/bash
/bin/distrib_ps $* -p $(grep -l "^envID:[[:space:]]*0\$" /proc/[0-9]*/status | 
    sed -e 's=/proc/\([0-9]*\)/.*=\1=')

What do you think of it ?

No no no no! We are certainly not going to modify/move or anything like that /bin/ps. That is the most un-good-citizen-like thing I can think of :)

Ha, I didn't search properly the internet; somebody did implement that before us
https://groups.google.com/forum/#!topic/help-cfengine/h098EgAusoA
http://pastebin.com/ipTeh1Mk

We could improve on that, with Virtuozzo and OpenVZ, and use /bin/vzps only if this file exists, and we are on the host

Great stuff. Thanks Nico.

Let's give the CFEngine guys the weekend + 1 or 2 days to respond and guide us away from any obvious blunders or conflicts with upcoming changes their side, then patch our build of rudder-agent to include this.

Updated by François ARMAND over 10 years ago

Just a quick remark: in my test (done by hand, so not scientific at all), time on vzps and the "poor man vzps (fast version)" on http://openvz.org/Processes_scope_and_visibility are almost identical (and both are 4 times what vanilla ps takes)

So I'm wondering if we really should rely on vzps, which is a new package to install, seems broken every even weeks, and is not available on all system.

What do you think?

Updated by Andrew Cranson over 10 years ago

I've tested this on a few production servers, and the results are similar to this every time:

Poor man's vzps (fast version):

real 0m0.458s
user 0m0.096s
sys 0m0.365s

vzps -E 0:

real 0m0.034s
user 0m0.008s
sys 0m0.026s

It's roughly 10-15x faster to use vzps every time from what I've seen (Parallels Cloud Server 64-bit).

Updated by François ARMAND over 10 years ago

Yes, Nicolas explained to me that there is several implementation of vzps, at least one being in perl (roughtly as fast as the shell script) and one in C (10-15x faster than the shell script). I wasn't aware of the different version.

It seems that Virtuozzo comes with the fast C vzps version.

Updated by Nicolas CHARLES over 10 years ago

Francois, it's not a problem to point to vzps, as we could detect in Rudder if the file is there, and if not, put in place the "poor man vzps".
Unless you have another solution ?

Ha, there are some correction to do, as the CFEngine team had some remarks.

Meanwhile, Andrew, as you have a "real" vzps, could you tell me what's the output of the next command ?

/bin/vzps -E 0 -o user,pid,ppid,pgid,pcpu,pmem,vsz,ni,rss,nlwp,stime,time,args

I'd like to be sure of the compatibility level of this patch ...

#27

Updated by Jonathan CLARKE over 10 years ago

As an exception to our standard bug fixing policy, despite the fact that this bug is also present in Rudder 2.4.* branch which is still maintained until January 2014, I am going to accept this fix only into the Rudder 2.6.* branch for now. The reason for this is that developing the fix on the 2.4.* branch would take considerable extra work, and it is urgent to provide a fixed version on the current stable branch, so I don't want to delay that any longer.

This does not mean this bug should not be fixed on the 2.4.* branch, just that it will be fixed first on 2.6.* branch. I will create a separate ticket to track the back-porting effort.
